Old Overholt is a long produced American rye whiskey distilled by A. Overholt & Co, currently a subsidiary of Beam Inc., at the Jim Beam distillery in Clermont, Kentucky. Old Overholt was originally distilled in Broad Ford, Pennsylvania, 35 miles southeast of Pittsburgh. It is one of the few straight rye whiskies available at most liquor stores in the United States. The company claims to have been established in 1810, and the bottle states that at 80 proof (40% alcohol), this is a four year aged whiskey. The whiskey is named for Abraham Overholt, a farmer and distiller and later, grandfather of the American Industrialist Henry Clay Frick.
Parodied in a Warner Brothers cartoon, and in the Terry Pratchett novels The Dark Side of the Sun and Soul Music as "Old Overcoat".
It was the so called "Medicinal Alcohol" of the US Navy during WWII.
It is reputed to have been the alcoholic beverage of choice of the gunfighter and gambler Doc Holliday.[1]
